invalid_client

I'm trying to implement Apple Login using OAuth through the following URL:

https://appleid.apple.com/auth/authorize

I use the client_id parameter, which corresponds to the Service ID created under Identifiers in the Apple Developer portal.

The problem is: an existing Service ID works fine, but when I create a new Service ID and try to use it, I get an invalid_client error as soon as the authorization window opens.

I've double-checked everything, but I can't figure out what the issue is. Has anyone else experienced this or knows the cause?

Any help would be greatly appreciated!

This has been an issue for me as well since last week.

Really need Apple to get on this issue as it seems to be affecting multiple people.

This is literally a requirement for launching on the App Store and if Apple can't provide this service how are we supposed to launch apps?

I'm experiencing the same issue. I've contacted Apple Support via email but haven't received a response yet. I also submitted a report through the Feedback app, but there has been no follow-up so far

Same problem here, I need to change callback URLs for sign in with apple and it is not being registered. Then I created a new Service ID to swap with the old one and the new one is not being registered at all

Same Issue over here, driving me nuts and found out everyone are experience the same issue.

ah im not alone
